Talking of candles on trees. I remember a small brass fan about the size of a jam pot lid with little brass angels hanging off it. the candles were below and the convection heat turned the fan, spinning the angels and casting shadows. Simple but affective.
They did the same thing with the old electric fires with the plastic coal affect on top to make it look like it was burning.
Obviously they used the heat of the electric bulbs and not a real flame on the fire.
